Title: Circuit for presetting asynchronous signal data
Inventor: OBATA HIROSHI
IPC: H03K5/00
Filed: 1985-03-30
Abstract: PURPOSE:To preset a data processed by both leading and trailing edges of a master clock with an asynchronous delayed data by providing the 1st and 2nd delay circuits, a half block counter circuit and a latch circuit. CONSTITUTION:The asynchronous signal DRF fed to a shift register 31 is retarded up to the leading edge of the master clock Cpm and the asynchronous signal DRF fed to a shift register 32 is delayed up to the trailing edge. Both the delayed data are fed to a latch circuit 34 to drive flip-flops FF1-FF4 thereby presetting the data at every half clock generated by a counter circuit 33. Thus, the data process by both the leading and trailing edges of the master clock are preset by the delayed asynchronous signal without losing the resolution.

Title: Color solid-state image pickup device
Inventor: TANAKA NOBUYOSHI
IPC: H04N9/04
Filed: 1981-05-07
Abstract: PURPOSE:To reduce the generation of a ghost image by providing a light shielding part having prescribed width at the circumferential edge part of the light incidence flank of a color filter, and suppressing total reflection. CONSTITUTION:A light shielding part 12 having prescribed width is formed annularly along the external flank of a color filter 6, namely, the circumferential edge part on the light incidence side. This light shielding part 12 cuts off a light beam 10 incident to the side of the circumferential surface 11 of the filter 6, and consequently any total reflection is not caused on the flank of the filter at all, so that no unnecessary ghost image is formed. When the light shilelding part 12 is too wide, ghosts are removed sufficiently, but imaging luminous flux at the circumference of an image pickup part is eclipsed to cause a shading phenomenon, so the best width should be set.

Title: Magnetic head supporter
Inventor: OKITA MASAO
IPC: G11B17/32
Filed: 1989-03-22
Abstract: PURPOSE:To prevent the damage of a disk by forming grooves to annular projections existing on a head support and disposing the groove apertures on an upstream side and downstream side in the rotating direction of the disk to the positions where the apertures do not overlap on the rotating loci of the disk. CONSTITUTION:The respective aperture positions of the grooves 12, 13 formed on the projections 3, 4, on the upstream side and downstream side viewed from the rotating direction of the disk, are so disposed as not to overlap on the rotating loci E, F corresponding to the innermost peripheral track position of the disk. The curvature of the loci increases and the overlap quantity of the end parts G, H on the loci increases when the part in contact with the inner end part G of the projection 3 on the outer side comes into contact with the outer end part H as well as the disk seeks to the outer peripheral side beyond the same. The generation of the part which does not come into the projection 3 is thus obviated. The intrusion of the disk to the grooves 12, 13 by deformation does not, therefore, arise. The damaging of the disk surface and the failure in writing and reading out of the signals are prevented in this way.

IPC: H04B17/40
Filed: 1990-03-17
Abstract: PURPOSE:To decide a failure repeating section only by one test by identifying addresses allocated to respective repeating installations in a test data string. CONSTITUTION:A test pattern string generated from a test pattern generating circuit 1 is outputted from the sending output OUT11 of a tester and inputted to the receiving input IN21 of the repeating installation, and when a test pattern detecting circuit 4 in the repeating installation detects the inputted pattern string, an address inserting circuit 5 inserts an address allocated to the repeating installation concerned to the address part 9 of said test pattern and a loop back circuit 7 loops back the test pattern string from a transmission output OUT22 through a receiving input IN11. At the time of detecting the address of the succeeding repeating installation in a pattern string received from the succeeding repeating installation, loop back operation is not executed. Consequently, the transmission quality of a section up to the repeating installation whose address is detected and the existence of a failure in the repeating section of the succeeding repeating installation can be decided.

Title: Switch control circuit
Inventor: AWAJI TOSHIAKI
IPC: G01R31/26
Filed: 1993-03-26
Abstract: PURPOSE:To generate a stable ternary waveform by controlling a switch element through a constant current circuit only when a switch control voltage is generated, supplying the constant current, which flows to the switch element, to a switch control voltage generating resistor connected to a plus voltage side and a minus voltage side, and generating a switch signal which deviates to the plus voltage side and minus voltage side. CONSTITUTION:This circuit operates as a voltage shifter while switch elements 15A-15C, and 22A-22C which constitute a 2nd switch element group 15 and a 4th switch element group 22 are ON, and the currents which flow to switch control voltage resistor groups 16 and 23 in the ON state are limited by constant current circuits 19 and 24 to constant currents. Therefore, the switch control voltages VA, VB, and VC generated by the respective switch control voltage resistors are stabilized at constant values. When transistors(TR) are used as the switch elements, the TRs are superior in temperature characteristics to constant-voltage diodes. Consequently, the supplied currents can be prevented from varying owing to temperature variation of the switch elements.
